Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to bearing speed reducer cages. Background Technology

[0002] The cage of a bearing reducer is a bearing component that partially encloses the rolling elements, serving to isolate and guide them. It not only prevents the rolling elements from colliding and rubbing against each other, but also ensures that the rolling elements are evenly distributed on the raceway, thereby reducing friction and heat generation, and improving the bearing's service life and efficiency.

[0003] Existing bearing reducer cages mainly adopt a tapered frame structure. This design effectively keeps the tapered rollers arranged in an orderly manner on the fixed track within the ring. To reduce friction and improve lubrication, the cage surface is uniformly coated with lubricating grease.

[0004] In the prior art, the lubricating grease applied to the cage surface will be lost after high-speed friction. This results in excessive oil in the initial stage of lubrication. Excessive lubrication will cause the lubricating oil to generate excessive heat during high-speed rotation, increasing friction and temperature rise, and may even cause the oil film to rupture, thereby accelerating the wear and damage of the bearing. Insufficient lubrication in the later stage will cause the rolling elements and raceways inside the bearing to come into direct contact, increasing friction and wear.

[0005] Therefore, this application proposes a bearing reducer cage to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a bearing reducer cage, which aims to solve the problem in the prior art that the lubricating grease on the surface of the bearing cage will be lost under high-speed friction conditions, resulting in excessive lubrication in the early stage and insufficient lubrication in the later stage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A bearing reducer cage includes a retainer, an assembly is mounted on the outside of the retainer, a connecting groove is formed on the inner wall of the retainer, multiple movable channels are formed on the inner wall of the retainer, and a movable hole is formed on the inner wall of the retainer near the movable channel, with a ball movably connected to the inner wall of the movable hole.

[0009] As a further description of the above technical solution:

[0010] The assembly includes an outer ring, the inner wall of which contacts the outside of the retainer, and the outside of the retainer has multiple receiving grooves.

[0011] As a further description of the above technical solution:

[0012] The inner walls of the plurality of receiving slots are each fitted with ball bearings, and the retainer is internally connected with a collar.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the retainer is provided with multiple movable grooves, and each of the inner walls of the multiple movable grooves is movably connected to a movable bead.

[0015] As a further description of the above technical solution:

[0016] The interiors of the plurality of movable slots are connected to the interiors of the connecting slots, and the interiors of the plurality of movable channels are connected to the interiors of the connecting slots.

[0017] As a further description of the above technical solution:

[0018] The outer surfaces of the multiple rolling balls are in contact with the outer surfaces of the retainer, and the outer surface of the retainer has multiple gap grooves.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, the lubricant is added along the edge of the retainer, allowing excess lubricant to flow along the surface of the retainer into the connecting groove and the interior of the moving channel. During machine operation, when the external structure contacts the ball, a small amount of lubricant will flow out along the movement of the ball. The bearing reducer retainer has a groove to accommodate the lubricant, and the use of the ball to control the amount of lubricant to prevent rapid loss ensures that a stable oil film is formed between the rolling elements and the retainer, reducing friction and wear.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1 to 3 This utility model provides an embodiment of a bearing reducer cage, including a retainer 2, which supports and guides the rolling elements and ensures that these elements can move on the proper trajectory, thereby reducing friction and wear and extending the service life of the bearing. The retainer 2 is typically made of high-strength, wear-resistant materials, such as metal or engineering plastics, to withstand stress under high-speed rotation and heavy-load conditions. An assembly is mounted externally to the retainer 2, including an outer ring 1. The inner wall of the outer ring 1 contacts the outer side of the retainer 2. As part of the cage, the inner wall of the outer ring 1 is in close contact with the outer side of the retainer 2, forming a stable structural frame. This design helps maintain the correct position of the rolling elements and prevents them from falling off or becoming misaligned during operation.

[0029] The retainer 2 has multiple receiving grooves 5 on its exterior. These grooves 5 are specially designed structures on the retainer 2 for accommodating and securing the balls 3. The inner walls of each of the multiple receiving grooves 5 are fitted with balls 3 (as shown in the attached diagram). Figure 1 These grooves must be precisely designed to ensure that the balls 3 can roll freely within them while being properly constrained to prevent them from deviating from their intended trajectory due to centrifugal force or other external forces. A retainer 2 is internally connected to a collar 4, with the outer surfaces of the multiple balls 3 contacting the outer surfaces of the collar 4 (as shown in the attached diagram). Figure 1 The retainer 2, also known as the retainer ring 4, is another key component. It contacts the outer surface of the balls 3 and together they form the rolling interface of the bearing. The design and material selection of the retainer ring 4 are crucial for reducing friction, improving wear resistance, and ensuring the overall performance of the bearing. The retainer 2 has multiple clearance grooves 6 on its outer surface, which are used to maintain a certain distance between the multiple balls 3.

[0030] Reference Figure 4The retainer 2 has a connecting groove 9 on its inner wall, which stores most of the lubricating oil and provides a channel for the flow of lubricating oil. The retainer 2 also has multiple movable channels 12 on its inner wall, which communicate with the interior of the connecting groove 9. The design of the connecting groove 9 and the movable channels 12 allows the lubricating oil inside the retainer 2 to flow to various parts requiring lubrication. A movable hole 11 is provided on the inner wall of the retainer 2 near the movable channels 12, which stores lubricating oil. A ball bearing 10 is movably connected to the inner wall of the movable hole 11, and the ball bearing 10 applies lubricating oil to the contact surface during friction.

[0031] The inner wall of the cage 2 has multiple movable grooves 8, and each groove 8 is movably connected to a movable ball 7. The movable ball 7 controls the amount of lubricating oil during lubrication to prevent excessive flow. The interiors of the multiple movable grooves 8 are connected to the interiors of the connecting grooves 9, allowing lubricating oil to flow through the movable grooves 8 to other structures of the cage 2 for lubrication. The balls 10 in the movable holes 11 and the movable balls 7 in the movable grooves 8 are designed to further optimize the cage's performance, providing additional support and guidance during bearing operation, while also helping to distribute loads and reduce stress concentration at individual points.

[0032] Working principle: During use, multiple rolling balls 3 are first installed inside multiple receiving grooves 5 outside the retainer 2. Then, the retainer 2 is installed inside the outer ring 1, and the retaining ring 4 is installed inside the retainer 2. Lubricating oil is then added along the edge of the retainer 2, allowing excess lubricating oil to flow along the surface of the retainer 2 into the connecting groove 9 and the moving channel 12. During machine operation, when the external structure contacts the rolling balls 10, a small amount of lubricating oil will flow out along the movement of the rolling balls 10. The bearing reducer retainer has a through groove to accommodate the lubricating oil, and the rolling balls 10 control the amount of lubricating oil to prevent rapid loss. This ensures that the lubricating oil forms a stable oil film between the rolling elements and the retainer, reducing friction and wear, while preventing excessive loss of lubricating oil and maintaining proper lubrication. Controlling the flow of lubricating oil through the rolling balls 10 also avoids the problem of temperature rise caused by excessive oil, thereby improving overall operating efficiency and stability.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
